To accurately track the efficiency of any solar installation, a high-quality weather station is a necessity. The WattMetrics weather sensor platform is designed specifically for solar projects. It provides system builders with an accurate, reliable, flexible and affordable weather station solution.
System Efficiency Metrics
Adding a weather station to a project enables the calculation of real-time total system efficiency. See this blog post to learn more: System Efficiency Metrics.
Single-Cable Power and Communications
Power and communications are provided to the station via a single cable, making installation quick and easy.
Zero Configuration
All instruments are pre-configured and pre-calibrated. Just connect the combined power+communications cable to a WattMetrics Universal Acquisition Agent and you're done.
Embeddable Data
Interactive charts with live weather data are easily embeddable in any website.
Unmatched Accuracy
Like all WattMetrics data sources, recorded weather station readings are heavily oversampled, ensuring highly accurate data.
Wind, Humidity and Pressure Sensors Optional
Our flexible platform allows customers to choose the sensors that best fit their specific project.
Multiple Irradiance Sensor Options
The standard irradiance sensor offers a great balance between affordability and accuracy. For more demanding projects, higher-accuracy sensors are available.
Heavy-Duty Instrument Tower
18 gauge steel tubing is zinc-chromate-polymer galvanized with gold irridited leg braces, mast collars, and connecting components.
